A solution of benzyl-4-(aminomethyl)piperidine-1-carboxylate (EXAMPLE 13, Step 1, 0.10 g, 0.40 mmol), 2-chloro-5-fluoro-pyrimidine (0.053 g, 0.40 mmol) and triethylamine (0.11 mL, 0.81 mmol) in DMF (0.5 mL) was heated at 100° C. for 6 h, then concentrated in vacuo. The residue was purified by silica gel chromatography (10 CH2Cl2: 1–20 IPA: 89–70 hexane) to give 4-[(5-fluoro-pyrimidin-2-ylamino)-methyl]-piperidine-1-carboxylic acid benzyl ester.
